In peritoneal dialysis, blood is filtered inside the body after the abdomen is filled with a special cleaning solution. It means that blood is cleaned by using lining of abdominal area as a filter. This method allowed blood to be filtered while patient carry out their everyday activities.
Before first peritoneal dialysis session, doctor will create access to abdominal area by making small surgical cut, most often at the side of belly button. A plastic tube called a catheter is inserted into the stomach and nearby organ. This is called peritoneal cavity.
HOW PERITONEAL DIALYSIS WORKS??
In peritoneal dialysis, peritoneum (natural lining of
abdomen) acts as dialysis membrane. Small operation is needed to insert
a catheter into the abdomen. The wastes and extra
fluid are removed from the body into the lower bag when the dialysis
solution is drained off. The fresh dialysis
solution from the top bag is drained in into the peritoneal cavity. This is
called an ‘exchange’- fresh fluid replacing old.
- The draining and filling process, called an exchange take about 30 to 40 minutes. Patient will need 4 exchanges per day.
- There are two main types of peritoneal dialysis:
a) Continuous Ambulatory Peritoneal Dialysis
(CAPD).
This type of dialysis is done without a machine. Dialysis solution is
placed into the catheter and patient can go for their everyday activities or
sleep. It is done four or five times a day.
b) Continuous Cycler-assisted Peritoneal Dialysis
(CCPD).
This type of dialysis uses a machine called a cycler to fill and drain
the solution from the stomach, usually done while sleeping.
- Peritonitis- inflammation of peritonitis
- Weight gain
- Due to the use of dextrose solution and fluid overload in the body because of imbalance in and out fluid.
- Dehydration
- Due to drinking too little, causing too concentrated dextrose solution
